The disks 6 are provided with aligning bearing Shoulders are formed on the driving pin, and

provide a bearing surface for the balls 35 onwhich the bearing 32 rests. At the opposite end of the driving pin, is a bearing 36 held in position by the nut 31, the bearing 36 providing a bearing surface for the balls 38, to insure free rotation 01' the driving pin on its piston rod.

The cylinders 25 are positioned in circular lines on the outer surfaces of the body of the engine and are spaced equidistant from a central bore of the body, in which the engine shaft 9 operates, and while I have in the present showing, illustrated four cylinders, the number of cylinders may be varied, to meet various engine requirements.

What is claimed is:

In a crankless internal combustion engine, a body, an engine shaft extending through the body, a flywheel having a cam groove formed in the periphery thereof and extending around the said flywheel, secured on the engine shaft and being disposed within the body, a plurality of pairs of opposed engine cylinders mounted on the body, the cylinders of each pair being in direct alignment, pistons operating within the cylinders, a connecting rod common to the pistons, operating in the respective pairs of cylinders, spaced parallel guide members secured between the inner ends of adjacent opposed cylinders, said guide members having longitudinal grooves formed in the inner surfaces thereof, a driving pin mounted on each rod, and including a bearing member. an annular rib on the bearing member, said annular rib being disposed within the grooves of adjacent parallel guide members, said bearing member having upper and lower ball bearing grooves, a driving pin extending through said bearing member and having ball bearing grooves cooperating with the grooves of the bearing member in housing ball bearings, providing an anti-friction driving pin, and said pin having a reduced end providing a shoulder, said reduced end of the driving pin being adapted to operate in the cam groove of the flywheel, converting reciprocating movement of the pistons to rotary movement of the flywheel and engine shaft.
